Abstract

METODO DE SOLDADURA POR REFLUJO EFICAZMENTE DE UNO O MAS DISPOSITIVOS (11) PARA UNA TARJETA DE CIRCUITO IMPRESO (12) CON UN HORNO DE CALENTAMIENTO POR CONVECCION (13), CADA DISPOSITIVO (11) TIENE UNA PLURALIDAD DE PATILLAS DE CONEXION ELECTRONICA PARA FIJACION EN LA PLACA (15) QUE ESTAN PARA SER SOLDADAS DENTRO DE LAS APERTURAS DE UNION RESPECTIVAS (17) DE LA TARJETA DE CIRCUITO IMPRESO (12) PARA CONEXION ELECTRONICA, EL METODO COMPRENDE: (I)COLOCACION DE UNA PASTA DE SOLDAR EN CADA UN A DE LAS ABERTURAS (17); (II) ENSAMBLAJE DEL DISPOSITIVO (11) EN LA TARJETA DE CIRCUITO IMPRESO (12) POR POSICIONAMIENTO DE LA PLACA (28) DEL DISPOSITIVO (11) A LO LARGO, PERO ESPACIADOS EN RELACION, LA TARJETA DE CIRCUITO IMPRESO (12) PARA DEFINIR UN ESPACIO PLANO (30) ENTRE ELLOS, CON LAS PATILLAS (15) INTRODUCIENDOSE EN LAS ABERTURAS (17) Y DENTRO DE LA PASTA DE SOLDAR PARA FORMAR ASI UN CONJUNTO; Y (III)PASAR EL CONJUNTO POR EL HORNO DE CALENTAMIENTO POR CONVECCION (13) DURAMENTE DURANTE UN PERIODO DE TIMEPOR PARA DERRETIR LA PASTA DE SOLDAR Y FORMAR UNA CONEXION VALIDA HASTA QUITARLO DEL CALENTAMIENTO CORRECTIVO, DICHO PASO ES SACADO POR EL USO DE CARACTERISTICAS DE LOCALIZACION DEL CALENTAMIENTO CORRECTIVO QUE GUIA EL FLUJO DE CALOR CORRECTIVO ENTRE LA PLACA Y LA TARJETA PARA MEJORAR EL CALENTAMIENTO CORRECTIVO DE LA PASTA DE SOLDAR DESDE AMBOS LADOS DE LA TARJETA.METHOD OF EFFECTIVELY REFLUX WELDING OF ONE OR MORE DEVICES (11) FOR A PRINTED CIRCUIT BOARD (12) WITH A CONVECTION HEATING OVEN (13), EACH DEVICE (11) HAS A PLURALITY OF ELECTRONIC CONNECTION PINS FOR ATTACHMENT THE PLATE (15) THAT IS TO BE WELDED WITHIN THE RESPECTIVE UNION OPENINGS (17) OF THE PRINTED CIRCUIT CARD (12) FOR ELECTRONIC CONNECTION, THE METHOD INCLUDES: (I) PLACEMENT OF A WELDING PASTE IN EACH ONE OF THE OPENINGS (17); (II) ASSEMBLY OF THE DEVICE (11) IN THE PRINTED CIRCUIT BOARD (12) BY POSITIONING OF THE PLATE (28) OF THE DEVICE (11) ALONG, BUT SPACED IN RELATION, THE PRINTED CIRCUIT BOARD (12) TO DEFINE A FLAT SPACE (30) BETWEEN THEM, WITH THE PINS (15) INTRODUCING THEMSELVES IN THE OPENINGS (17) AND WITHIN THE WELDING PASTE TO FORM A JOINT; AND (III) PASS THE ASSEMBLY THROUGH THE CONVECTION HEATING OVEN (13) DURINGLY DURING A TIMEPOR PERIOD TO MELT THE WELDING PASTE AND FORM A VALID CONNECTION UNTIL REMOVING IT FROM THE CORRECTIVE HEATING, SUCH A STEP IS TAKEN OUT OF THE USE OF CHARACTERISTIC LOCATION OF CORRECTIVE HEATING THAT GUIDES THE CORRECTIVE HEAT FLOW BETWEEN THE PLATE AND THE CARD TO IMPROVE THE CORRECTIVE HEATING OF THE WELDING PASTE FROM BOTH SIDES OF THE CARD.
